Water tank sterilization in Al Quraiyat Jeddah

Al Quraiyat is an old densely-built popular quarter in south Jeddah within the Al Jamiah sub municipality. Apartment buildings are old and rooftop tanks suffer from thick sediment. The quarter is surrounded by educational landmarks and daily-use shops, and tanks here need regular cleaning and sterilization due to age and heavy use.

  • Potable-rated materials

    Linings and disinfectants cleared for drinking water tanks, not general-purpose products.

  • You get the downtime first

    How many hours the tank is out of service, told before we start rather than after we finish.

  • A first-draw flush

    We run the first draw off after refilling, and the tank is not handed back until the water runs clear.

  • Ground and roof tanks

    Villas, apartment blocks and premises that need a written record of each visit.

Why the job is different in Al Quraiyat

Tanks here are very old and contain thick sediment because of building age and iron pipes that rust rapidly in the coastal climate. The method is set out in full on how we approach Water tank sterilization.

The first reason

Very old apartment buildings with small rooftop tanks

Buildings in Al Quraiyat were built at least thirty or forty years ago. Rooftop tanks are small with cracked internal walls heavily caked in sediment. Roofs are cramped and tanks face direct sunlight all year round.

The second reason

Rusted iron pipes from tanks to street outlets

Pipes connecting tanks to outlets are old iron and heavily corroded. Rust eats through the walls from inside. Water flows through layers of white and red rust, giving it a metallic taste and cloudy appearance.

The third reason

Daily shops and restaurants provide moisture and added contamination

Small shops, restaurants and cafes dot every corner of the quarter. Moisture from cooking and washing raises humidity levels, and bacteria grow faster in the tanks.

The character of Al Quraiyat

Apartment district: residential blocks, repeated floors and shared entrances

Al Quraiyat is a very old popular residential quarter with closely-packed buildings and small tanks on narrow roofs. Old rusted iron pipes and rust are a major problem here. Cleaning and sterilization must account for the fact that the pipes are the primary contamination source.

Before treatment

What we read inside the tank before anything starts

An old densely-built popular quarter in south Jeddah within the Al Jamiah sub municipality, lying between Al Thaalibah to the west and Al Nazlah Al Sharqiyah to the east. Older apartment buildings are closely packed and everyday shops and services line the streets. The College of Telecommunications and Electronics stands nearby.

Fine wet sand seen close up

Sediment on the floor

Red and brown sediment collects in the tank from very old rusted iron pipes. Water passes through a thick rust layer before reaching the tank.

A concrete wall carrying a damp green layer

The slime film on the wall

White cloudy sediment comes from natural minerals and calcium, increasing in summer when evaporation concentrates the dissolved solids.

Light and heat

Green and black algae grow on tank walls because the quarter is old, heat is intense and moisture from shops and restaurants is very high.

A concrete surface carrying fine cracks

The lining and any cracking

Sharp foul odour comes from decomposition of organic matter and anaerobic bacteria in thick sediment and stagnant water.

Cracks in tank walls and loose covers allow dirt, insects and dust to enter from old roofs.

What shows up at the tap

Constant water turbidity signals that sediment is releasing fine particles or bacteria are floating in the water. It needs deep cleaning and strong sterilization.

How we work

  1. 1

    Inspect and record the condition

    We open the hatch and work through what the tank is made of and how big it is, how deep the sediment lies, the state of the lining, whether the lid and the overflow seal, and whether there is a crack that has to be repaired before any sterilizing.

  2. 2

    Drain and lift the sediment out

    The water goes out, then the silt and sand are lifted off the floor by suction rather than pushed toward the outlet, because pushing them sends them into the house pipework and the heater.

  3. 3

    High pressure wash

    Walls, floor, corners and the area around the outlet, until the slime film is completely gone. This is the step that makes the sterilizing after it mean anything.

  4. 4

    Sterilize, rinse, then return to service

    The sterilizing agent goes onto the walls, the floor and the underside of the lid and is left for its contact time, then we rinse, refill and run the furthest tap until the whole line is clear.

What water tank sterilization includes

  • A technician inspecting with a flashlight

    A recorded inspection

    Material, capacity, sediment depth, the state of the lining, the lid and the overflow, all before any work begins.

  • A metal floor drain

    Draining and sediment removal

    The water out, and the silt and sand lifted off the floor instead of being pushed into the outlet and the house pipework.

  • A spray nozzle in close detail

    High pressure washing

    Walls, corners and around the outlet, until the biofilm that no disinfectant penetrates has gone.

  • A spray nozzle in close detail

    Sterilizing the internal surfaces

    A sterilizing agent meant for drinking water tanks, applied to the walls, the floor and the underside of the lid, and left for its contact time.

  • A clean kitchen counter after treatment

    Line flush and aftercare

    Rinse, refill and a flush from the furthest tap, when the water is usable again, and what to change in the filter afterwards.

  • The visit report being written on a clipboard

    The next cycle

    We agree the right interval for your tank from how it is filled, how much sun it takes and the condition of the lid.

What is different about Al Jamiah Sub-Municipality

Al Jamiah sub municipality spans the older south of Jeddah. Planned districts such as Al Fayha, Al Thaghr and Madain Al Fahd sit beside crowded popular quarters like the Nazlahs and Al Quraiyat, and beside cleared or clearing land in Ghulail, Petromin and Al Thaalibah awaiting redevelopment. Apartment buildings stand close together above dense runs of shops and restaurants along Old Makkah Road and Prince Majid Road. Drainage in the popular quarters is ageing, humid air drifts in from the port and refinery side to the west, and the flat low lying ground holds rainwater in narrow streets.

Questions about this district

Why does water sometimes turn reddish in Al Quraiyat?

Very old iron pipes rust from the inside and red oxide mixes with the water. This signals the pipes are near the end of their working life.

Does district humidity cause tank contamination?

Strongly yes. High humidity from shops and restaurants creates ideal conditions for bacteria and algae inside tanks.

Does cleaning one tank improve water quality for the whole building?

It improves it but may not solve it entirely. If pipes are rusty they will add new contamination continuously even after tank cleaning.

How many times per year does the tank need sterilization here?

At least three times yearly, one per season. The district is old, pipes are rusty and bacteria multiply at high speed.

What is the difference between red sediment and white sediment?

Red sediment comes from iron rust in the pipes, white sediment from natural minerals and calcium. Both affect water taste and colour.

Will replacing pipes solve the problem permanently?

Yes completely. Modern plastic or genuine copper pipes will not rust and will not add new contamination. Tank cleaning and sterilization after pipe replacement yields clean water.

How much does water tank sterilization in Al Quraiyat cost?

It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Al Quraiyat.
